Abstract: The present invention relates to an attachment device having a sewing ring frame and a locking element mounted on the sewing ring frame. The locking mechanism includes a flange element projecting from the outer surface of the sewing ring frame and a retractable locking pin projecting towards the interior of the sewing ring frame. The flange is coupled to the locking pin and the biasing element. The locking mechanism is transitionable between a locked configuration in which the locking pin is in an engaged position to an unlocked configuration in which the locking pin is in a disengaged position.

Abstract: A control circuit for controlling a pump speed of a blood pump implanted in a patient including a processor in communication with the implanted blood pump, the processor having processing circuitry configured to reduce a pump speed relative to a standard set speed based on a timing of a systole phase of the patient, the systole phase including a first segment during which a ventricular pressure is at its greatest and a second segment occurring after the first segment during which the ventricular pressure is at its lowest, the pump speed being reduced during the second segment.
